HTTPS2, ERR_QUIC_PROTOCOL_ERROR 200, ChunkLoadError

The problems started around 2 months ago. One dev told me it's the T-Mobile - CF Server in Warsaw (I'm from Poland) problem. Can someone confirm?

Also, important to note is that the websites load perfectly fine on all devices/browsers, but once I log in/authorize my DC account, they slow down

There's no known issues at the moment - https://www.cloudflarestatus.com/. That error doesn't make a whole lot of sense anyway

ERR_QUIC_PROTOCOL_ERROR

is HTTP/3, which is QUIC, not HTTP/2

but once I log in/authorize my DC account, they slow down

Log into what? Your website's backend? If so sounds like an origin issue
