I bet it is MTU related. Try lowering MTU on that interface (you cannot do it separately for IPv4 and IPv6 so it will change both, but that's not likely to be a problem) and get someone who has seen the problems to re-test.
thank you so much for your answer. I would have never ever thought about the MTU in this case. I used the default 1500. I talked to the technical support from the datacenter (Hetzner Online) and they asured me that 1500 is correct.
However, i have set the value to 1400 and asked some people who had the issue to re-test it. I will post the results of the test here so other people can find them via a search engine.
Thank you so much, very kind of you!
