ZAMG Integration says "500 Internal Server Error Server got itself in trouble" while trying to add an new station

[oe3arc]

The problem

After the two ZAMG sensors had timeouts during fetching data every now and then, I tried to add third station in order to verify whether it's related to specific weather stations or if it's a common problem.

Trying to add another station ended with the Error message "Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble".

After a restart the two stations showed data not available, an error in the log was shown: 2022-11-06 07:42:50.096 ERROR (MainThread) [homeassistant.components.zamg] Unexpected error fetching zamg data: ‘NoneType’ object has no attribute ‘get’.

Then I deleted the two stations and tryed to re-add a ZAMG integration via the GUI. This still ends up showing the error-message box "Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble"

The log says:

Same Problem here,

imported Zamg from config had undefined entites because the correlation did not happen correct, removing & trying to set it up initially worked afterwards (although with errors) and failed after a few minutes.

now when trying to set it up I get the same 500 which did not happen before

[killer0071234]

Hi, The problem with getting 500 internal server error is caused from a expired server certificate of https://dataset.api.hub.zamg.ac.at/ which the integration is using to read the data.

The certificate has expired today in the morning.

ZAMG seems to have renewed the certificates. I was able to add stations again right now.

[oe3arc]

monitored it a few hours - works now. issue closed.

Unfortunately the error described here also occurred with me yesterday.

See the parallel discussion in https://github.com/home-assistant/core/issues/81745. The ZAMG datahub looked bricked - right now I was able again to fetch data with the small test described in the above mentioned discussion.
