GUI error ISE 2.6 patch 7.

[Dustin Anderson]

I'm not sure when this started, but gat the attached error when trying to access ISE with chrome. I think it's a chrome issue as I can open it in firefox, but am at a loss of how to correct the issue. I've reset chrome and have it updated to current version. Anyone seen this error and have a direction I can look at?

Thanks,

Hi @Dustin Anderson 

As it happens, I saw this error yesterday on a customer network - ISE 2.3 p7 and using Chrome 86. It's not an ISE 2.6 issue.

When I click on the hyperlink in the error message then it does nothing. It was in a Citrix environment and I thought nothing of it. I switched to Firefox and was able to continue. I tried clearing cache etc - it restored some parts, but I eventually get the same error again. 

I have ISE 2.6 p7 in my lab and same Chrome version - no issues. 

I would bet that restarting the PAN would fix it.

Hi Arnie, I have come across the exact same issue. Out of the blue ISE 2.6 just stopped working in Chrome. Has anyone reloaded the PAN to see if that has resolved it? This is happening on all PSN nodes. 

It works ok in IE and Firefox.

When I try in Microsoft Edge browser I get the ISE login screen but also get the message:
