"We're unable to log you in because you may be offline". My internet is working fine. Is anybody else experiencing the same issue?

Quick update again - I stayed in a lobby for a while and it broke again (I can't play nor spectate games) . Seems very nondeterministic. I really want to avoid sniffing traffic to guess what is launcher doing bad.

I bet here's the culprit:

ethertype IPv4 (0x0800), length 590: $ROUTER_IP > $CLIENT_IP: ICMP 34.211.95.41 unreachable - need to frag (mtu 1492), length 556

Here's what I dug up.

In general re-launching client multiple times eventually helps. I guess (didn't sniff it, not worth the time :P) it's about DNS entry, probably one of endpoints works well.

I'm not certain anymore whether this is MTU issue - I have MSS clamping configured correctly. I also ensured that Windows has MTU set to the right value. Still nothing.

Riot - it's in your hands. I bet there's something going on, probably edge case that will not raise red alert automatically.
