Since a recent update (issue has only appeared in recent days, last application update 21/10, I'm getting various HTTP errors, but only intermittently on certain sites.
Initially this appeared to only be affecting Chrome but spread today to Edge.
Since the issue appeared in Edge, I deduced that it couldn't be the browser. Through a process of elimination, I got to the point of disabling the Web Shield in Avast. At this point, the errors instantly disappeared for sites I'd otherwise been unable to access.
The error I have seen today was ERR_HTTP2_FRAME_SIZE_ERROR however in recent days I've seen a slightly different HTTP2 error (I don't have a note & can't recall exactly what it was).
Has anyone else seen this/is it a known issue?
As soon as I re-enable the Web Shield, I start to see the issues again.
