HTTP Proxy error on webex registrered endpoints

[Jogesh-Rai2]

We are facing a unique problem with majority of our DeskPro's and other endpoints.

We are getting a random error "HTTP Proxy, The system is unable to connect through the configured HTTP Proxies".

We have checked the proxy configuration and it is correct. All devices are registered on cloud.

Any help will be very appreacited.

We have the same issue, first incident was around the 18th August.  Some units display it constantly others only when they join an MS Teams call.  Some have displayed in a SIP call.

If we go into the network settings on the device and change the url string for the proxy from http to https and save it goes away.  you have to revert the change quickly as the unit fails to register with the admin control hub.  however the message reappears on the next call.

I have checked the logs and can see the proxy timeout is happening due to the thousandeyes client which is enabled in CH>Device>Settings>Thousandeyes Client.

Do you also have it enabled?

We have the same problem, the error occurs very sporadically. In the proxy logs on the device you can see that the error occurs when a URL, in oure case its always <xy>.wbx2.com (which can be called in 99% of cases) times out. In the local proxy logs it also appears that the other side is no longer responding. The error is very difficult to reproduce. And it seems like the url host does not answere in some cases

We now have major issues this morning with all are units connecting to SIP calls and some units unable to join MS Teams calls via WebRTC.  Any of you having issue this morning?

If anyone from Cisco is reading this, I have SR 698002605 open (so far to no effect)

Has anyone resolved their issues? We are experiencing similar issues but have not been able to find anything that has changed. We opened a TAC case as well but were assured that the device is functioning as expected.

[steven-m]

We didn't get a fix for the issue but a work around to hide the message prompt on screen.  From Admin control hub select the impacted unit.  Go to configuration, User interface, diagnostic notifications and set the drop down menu to hidden.  This will stop the message on screen.  You can apply this individually or globally by selecting all units.  Cisco TAC told us our log files proved there was no Proxy issue on the units.

Thank you @steven-m., this will help I think. But would this also hide the future diagnostic notifications other then Proxy? I dont know if any major outage notification gets hide by this option that would impact the device and needed attention.
