Very slow App and cannot create or join session anymore

[Dimitri Muskens]

UPDATE

It indeed seems to be a routing issue or something like that.

I now tried and connected to my company VPN, routing all traffic through the VPN.
And guess what?
Everything is pretty fast and everything works - I can create sessions, ...

Counterchecked, disconnected VPN => slow again .

I also tried a rightclick "Inspect" and "Reload"  and could see in the network panel, that it could load a couple of resource pretty quickly, and then there are many requests that keep pending, over and over.
No idea, what this could be.
Do you have a firewall that maybe blocks me, if there are too many requests in parallel ? But does not block it, if I come from another IP ?

At least, this is a small success, even if it is not satisfying to have to use the VPN (I am in Germany, the VPN endpoint is in Switzerland).

So if you have another idea, what could be done, maybe on your server side - it would be great!

Honestly, with the info you've provided, I assume the solution is going to be on your side and can only be resolved by you (review your network settings/routing/port forwards/QOS/etc.). In perspective, too many people can use the program/app/platform without these issues for them to be general/server sided.
