Unable to enter Webex room on windows 10

graham.howe — Mon, 18 Mar 2019 00:29:23 GMT

I have been using windows 10 for the past month and regularly attend Webex meetings without problems. Suddenly this week I receive the following message on any windows 10 machine running any browser whenever I try to attend a meeting and even if I just try to enter my own room.

Invalid input or system error. Please try again or contact your site administrator.

I have tested IE11, Edge, Chrome and Firefox, and I have tried 3 different windows 10 computers (desktop, laptop and surface pro). If I use windows 7 or 8.1 machines I have no issue accessing meetings. I understand that windows 10 may not be fully supported yet, however I don't see why this was working fine on windows 10 up until the end of last week and has suddenly changed. I certainly have not changed anything across all three of the windows 10 devices in the last few days so am reasonably sure the problem is not caused by any action I have taken.

I'm having the exact same

I'm having the exact same issue, and all I could find on the internet was this post, and only one other on a Microsoft site: https://social.technet.microsoft.com/Forums/en-US/6a40f5e6-d440-488e-a23c-d6c956e66733/webex-in-windows-10-not-working-anymore-since-yesterday-aug-31?forum=win10itproapps

I've tested in all of the following browsers and they all fail:

Firefox 40.0.3
Chrome 45.0.2454.85 m
Microsoft Edge 20.10240.16384.0
Internet Explorer 11.0.10240.16431

NOTE: The strange thing is, if I use the Productivity Tools and click on Meet Now, it works fine. However, if I attempt to join someone else's meeting it fails as well since it tries to load it in a browser.

There is another thread on this topic at http://answers.microsoft.com/en-us/windows/forum/windows_10-update/trouble-using-webex-within-windows-10/8d45b5f1-ca0e-44f7-bba9-5f37eafc7024

Still no answers, but confirmation that others are experiencing the problem and that it is very recent.

When do you get this error

dpetrovi — Thu, 03 Sep 2015 14:47:25 GMT

When do you get this error displayed? When the meeting client starts to load, or even before you enter the name, e-mail, and optionally meeting password?

Have you tried removing the meeting client and trying to use the temporary client?

-Dejan

It happens immediately after

adamscarcella1975 — Thu, 03 Sep 2015 16:26:42 GMT

It happens immediately after I click on the big green "Enter Room" button and no I have not tried using the temporary client instead of the real client. If the only way to pick the temp client is to remove the real client, then I'll have to try that later today.

I can confirm that for me the

graham.howe — Thu, 03 Sep 2015 17:28:25 GMT

I can confirm that for me the problem exists regardless of whether the meeting client is installed or not. As soon as I either try to enter my own meeting room or click on the link in an invitation I see the error. If I try to attend a meeting from the meeting center (by entering the room ID), then I get the error after the green button is pressed.

Webex was working fine on

mbuttnerMSI — Fri, 04 Sep 2015 12:03:51 GMT

Webex was working fine on Windows 10 till this week. There was a windows 10 update and a productivity tools update at some point it stopped working.

Invalid input or system error. Please try again or contact your site administrator.

I can circumvent this by using Jabber or Productivity Tools. But if you try any browser, none of them work. Uninstalled Productivity Tools and Webex plugins several times, temp file, etc.. Webex is basically not functional on Windows 10 anymore.

Try this for webex issue -

rohitt841 — Wed, 09 Sep 2015 15:19:18 GMT

Try this for webex issue -

1) Use Chrome as web browser
2) In the chrome web store, search and install “IE tab” extension
3) First time you click on the logo an executable will be installed. From this point on, each time you click on the extension icon you will see a secondary bar in which you can add the webex URL by copy-pasting.
4) The program emulates internet explorer over chrome and makes webex work.

In IE 11 open dev tools [F12]

jazonhorsley — Thu, 10 Sep 2015 19:23:20 GMT

In IE 11 open dev tools [F12] under emulation set document mode to 9 and user agent string to IE 9 and it seems to work for me.

I get the error message

stephane.chappellier1 — Tue, 15 Sep 2015 17:52:20 GMT

I get the error message "Invalid input or system error. Please try again or contact your site administrator." using Windows 10.

Can you do something so that this is working.

Regards,

I am having the same issue,

peter_kooistra1 — Wed, 16 Sep 2015 16:59:18 GMT

I am having the same issue, but was able to join a meeting successfully in Chrome. To get it to work in IE11 I used this suggestion of changing the settings under the Dev Tools and it worked. One difference was I set the User agent string to IE10 instead of IE9 and it loaded the meeting properly. I also tried leaving the Document mode as 10 (default) and just changed the User agent string and it loaded correctly so it seems to be associated with the Document mode.

I posted a response on the

jbrianj80 — Fri, 25 Sep 2015 22:23:06 GMT

I posted a response on the Microsoft question here.

The underlying issue appears to be WebEx's parsing of the Windows 10 User Agent String:

Chrome User Agent:

Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36

Edge User Agent:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2486.0 Safari/537.36 Edge/13.10547

Both result in the error.

Overriding the User Agent String which is what is done by ieTab and the manual change in developer tools. resolves the issue:

Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)

I don't have access to the WebEx code to confirm but my speculation is that they are not properly handling the ##.# formatting after NT.

I have encounter this as well

erniasiacisco — Tue, 29 Sep 2015 09:14:22 GMT

I have encounter this as well. I have to use google chrome with IETab plugin install and I can join any webex meeting.

To use the ietab after installation, tyoe your webex url and click the ie tab icon in google chrome.

After that proceed to join or type a session number.

I have the same issue. The

Steve Simon — Wed, 30 Sep 2015 17:07:42 GMT

I have the same issue. The problem first started with IE ver 11.0.9600.17728

and then today Chrome ver Version 45.0.2454.101 m. I don't have any issues with Firefox

I did find a work around for both:

IE You need to go into Private Mode. You can setup your browser to always go into Private Mode. Search Youtube "Always Start Internet Explorer in Private Browsing Mode"

Chrome you have to Open a browser and in the Menu New incognito Window.

I hope Microsoft and/or WebEx resolves this quickly.

I logged a case when this

tim_wright — Thu, 01 Oct 2015 22:08:16 GMT

I logged a case when this broke for the isilon.webex.com web site several weeks ago. I was assured by Cisco support that this would be fixed by now:

"I wanted to give you an update on issue. I have checked with my engineering team on your issue. Windows 10 will not be fully supported until T30.1 As of now, we have partial support on T29.13.40. Currently at this time your site is on T29.13.34(isilon.webex.com) and at this time we do not support Windows 10 on that site. Please let me know if you have any additional questions."

and

"1.PRODUCTION Rollout Schedule : 8/14 - 9/11/15-T29.13.40 PRODUCTION Rollout Schedule : 9/4 - 9/21- T30.1"

So all sites not locked down should already be running the "fixed" version.

Cisco, please address this issue.

Is this workaround still

james.olcott1 — Tue, 06 Oct 2015 19:29:55 GMT

Is this workaround still valid?

Please emulate IE9 within IE

samiran.ghosh1 — Mon, 12 Oct 2015 16:12:30 GMT

Please emulate IE9 within IE (F12 - Developer mode) and the paste the WEBEX URL. This worked for me.

Yes this works.

samiran.ghosh1 — Mon, 12 Oct 2015 16:14:02 GMT

Yes this works.

This works in in Windows 10

nickm000111 — Thu, 15 Oct 2015 12:21:40 GMT

This works in in Windows 10 on edge for me

Note incognito in chrome did not work on the same machine

so we have workaround when will we get the fix?

The solution worked for me.

james.olcott1 — Fri, 16 Oct 2015 18:20:35 GMT

The solution worked for me. Had to re-launch Chrome, then all good! Thanks for the tip!
