GUI is not accessible on chrome and edge browser but able to open at firefox

GUI is not accessible on chrome and edge browser but able to open at firefox,

Showing below error.

X.X.X.X normally uses encryption to protect your information. When Chrome tried to connect to X.X.X.X this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be X.X.X.X, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

You cannot visit X.X.X.X right now because the website sent scrambled credentials that Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later.

New installation, pre-existing GW? What kind of WebUI are you trying to access?

Give us some details, please.

[aaryasamsung]

No new installation, I've just upgraded from 81.10 to 81.20 for this issue, but Issue still same.
And I'm trying to access my gateway by GUI on chrome or edge browser.

When did it start? Any changes as a trigger? What type of GW? 

[aaryasamsung]

It started around one week back, No changes were made except software upgrade, and the gateway is 6400.

If it works in Firefox and not the others after a major software upgrade, I have to ask, did you completely clear your cache in Google Chrome and Microsoft Edge? Are you the only one who accesses the GUI / has this problem or does it happen on multiple devices?

[aaryasamsung]

Yes, I tried to clear all cache data, but not working, Everyone is having the same issue.
