Additional context Ping works well. Grafana (172.16.95.15) on RaspberyPi also works well in my scheme.

Before clicking the search box in the template, it is a good idea to actually do a search 😀

Core 2.4.1 is known to have issues. Core 2.4.0 is known to be bad. Core 2.3.0 is the current stable one and appears to even work over VPN.

[Jason2866]

Maybe with core 2.4.2?

[Frogmore42]

2.4.2 is supposed to be better, but not many people have tried it. PlatformIO just made an update, but not a release, that makes it possible to use 2.4.2. I have not had a chance to try it yet.

[Dees7]

2.4.2 doesn't wok. 2.3.0 works well. Thanks.

[Jason2866]

I am testing 2.4.2 (with VSC Platformio) on some devices since yesterday. Looks good so far, but i doesnt use it via VPN. I control my devices via a HA System. This System i can reach over a secure way...

Closing this issue as Dees7 said that with 2.3.0 it worked. Thanks
