[planefinder] Failed to open connection to socket: Connection timed out (errno: 110)

[pflugj]

I have received a message from Plane finder:
Station 'xxxxxxxxxxxx' Offline - Plane Finder
we have not seen the above sharecode feed data to Plane Finder for over 48 hours.

looking at the log I found multiple entries like this:
[planefinder] 2026-07-02 11:18:09.202456 [V] Failed to open connection to socket: Connection timed out (errno: 110)
[planefinder] 2026-07-02 11:18:09.202505 [V] Failed to establish a data proxy connection. Receiver data cannot be sent!

Other feed ins like FR24 are working

Home Assistant OS Core 2026.6.4
Supervisor 2026.06.2
Operating System 18.1
Frontend 20260527.7

Any idea what is going wrong here?
Thanks
