AG browser plugin reports 'Something went wrong'


New Member
I'm using AdGuard for macOS application version release (CL-1.5.269).
In Google Chrome version 84.0.4147.135 (Official Build) (64-bit) I'm using AdGuard Browser Assistant 1.0.13.
When I open a new tab I see AdGuard enabled on this website.
When I type in a URL and go to that site (any site, it seems) I see in the AdGuard browser assistent: Something went wrong, contact Supprt.

The same is happening in Firefox ...

What could be wrong?

Hello there!

Looks like you are using Big Sur OS beta?
The release build of AdGuard is not compatible with this operating system. You made the right decision by installing Nightly.
