Having the same issue with some 3602i's that I converted to standalone also w/153-3.JF11. Can access all settings pages through the GUI, but when you change anything apply and click "OK" in the pop-up warning box, it displays "404 not found" in the text frame.

I would check using CLI whether those config changes are there on your AP? You can find any un-saved configs using below CLI command. In that way you know configs will be there, if not saved you can save it in CLI (write mem).

AAP1#sh archive config differences nvram:startup-config system:running-config

Also I would try with different image (eg ap3g2-k9w7-xx.153-3.JC)

Same problem here with a 2702i using the following software:

ap3g2-k9w7-tar.153-3.JK.tar

You can save config changes in the CLI and it will show on the WebGUI but if you try to change anything and apply via WebGUI it faults with 404 error page not found. Any solutions? I tried all browsers and even different machines same problem. I went as far as I formatted the AP and redownloaded software to make sure not corruption issue. This is very odd. Maybe revert to a previous version or this version has missing files. Any help would be appreciated or suggestions?

I would try a different image instead of tinkering around to try to fix this. If another image works, you pretty much found your answer. Faster to try a different image, you can always play around with the image later after you get it working.

I don't believe it is the software as the three other people on this thread and using completely different versions, so that would not make sense that it is the software. Has anyone had luck figuring out what the issue might be? Browser? Does the gui rely on specific HTML or standard to operate correctly? just throwing ideas out there. Thanks.

Spent some time trying to pin this down; tried a few things - formatted flash with clean IOS install (verified SHA to rule out corruption), tried older version... all with same error. Then I found a thread discussing this same 404 error/issue in regards to the "January 1, 2020 SSC" error:

https://www.cisco.com/c/en/us/support/docs/field-notices/704/fn70489.html

https://www.cisco.com/c/en/us/support/docs/security-vpn/public-key-infrastructure-pki/215118-ios-self-signed-certificate-expiration-o.html

Now trying to find a workaround that actually WORKS to see if this solves it. If anyone can come up with a step by step quick fix for this, that would be swell!

Downgrading to earlier firmware doesn't solve the issue. Appears to be the 1-1-2020 credentials expiration bug.

do you have a solution yet? i have the same error on my 1702i

Cisco just release for WLC 8.5.161.0 with a fix for the certificate bug. So I guess you will very soon (if not already) have a new image for the AP available to download.

I have the same Problem.

404 Not Found

Where ever in web UI you click Apply you get

WARNING:
The settings shown on this page will be updated.
Click 'OK' to continue.

And then 404 Not Found. On all browsers. On all units. Many people across the globe have it.

Reproducible 100%.

You have released software to the public without even a simple smoke test? - what does it tell about your Quality! ?

I have a May 2020 release on my 3502e, all the certificates are OK but I got the same problem.

Just an FYI for anybody searching around for a solution to the "404 error" problem and comes across this thread but is still confused, here's what I did to fix this problem!

For reference, here's what I was troubleshooting and where I'm at now:

Cisco IOS Software, C2700 Software (AP3G2-K9W7-M), Version 15.3(3)JJ1, RELEASE SOFTWARE (fc3)

I tried using different iOS versions as previously mentioned but this never fixed the actual issue where EVERYTHING i did resulted in a 404 error. I could reach the web portal no problem, but everything after that point was the issue...Quick setup? Nope, 404 error. Update some setting? Nope, 404 error, etc.

I tried, ap3g2-k9w7-tar.153-3.JI5.tar, JI6.tar, JPJ3a.tar, and JJ1.tar. JPJ3a.tar seemed to make the problem worse...things didn't seem right and MORE information was missing...but that could've been just me. I ended up settling with JJ1.tar as my final firmware (currently using)

So, what I think ultimately fixed the issue was this - https://www.cisco.com/c/en/us/support/docs/security-vpn/public-key-infrastructure-pki/215118-ios-self-signed-certificate-expiration-o.html#anc2

Reading through this was a HUGE help! (This was already posted earlier in the thread by another user, so not trying to steal thunder 😛 just...it was SO helpful!) Specifically section "Workaround 2 - Use the IOS CA Server to generate a new certificate"

I wanted to cover all my bases, so i zero'd my RSA keys and started with scratch.

I had to configure SNTP on the AP (used 0.us.pool.ntp.org) and synced up date/time then went through and followed the instructions in Workaround 2. I then generated my RSA general-keys and then configured SSH 2.0 and http secure-server...after doing all that, I was FINALLY able to log into the web portal and use the Easy Setup without running into the 404 error after every change!

I hope this helps somebody, because I've been banging my head against the wall trying to figure this out before stumbling across this thread! 😄

Thanks for posting your fix. It should help others whom might run into the same issue later on.
