Cant play anymore

Hey guys.
I cant play anymore.. Lichess always wants me to reconnect and nothing happen.
Also i cant see other people when they play. On the mainpage i got to refresh the side to see the currently highest game.

Everything else is working with my internet.

What browser are you using?

Chrome. It worked all the time..

noone can help`?

it doesnt matter on which page i am. theres always the "reconnect-text" in the corner.....

Try a different device on your same WiFi to see if it's your device or your internet.

Stare at this for 30 secs or so, to see if it's stable: lichess.org/lag

Nothing happen (Server ?ms, Player ?ms). I think its a problem with the router, but which problem?
When i play with my smartphone (wlan) its the same problem. without wlan i can play.

If you have admin rights to the router have a poke around and look for anything that's blocking/forwarding ports, enforcing no-gaming rules, look for what WiFi channel you're using (avoid higher than 10), try turning it off and on.
Try a different browser too.

Try direct connection without the router, this way you can at least localize the problem or rule it out.

Just wanted to check for new answers and the problem solved itselft.
Thank you guys!
