Script hung up after a while

[soenkekueper]

Hey,

the script is working on my openhabian raspberry pi in an docker container without any trouble.

But from time to time, when it was running a longer time (which i unfortunately can't determine exactly) the connection to ecovacs api and MQTT hangs up and it doesn't do anything.

The only thing i can figure out from the logs is that there is some problem to connect to the ecovacs api with status code 502.
This error occours up to six times a day:

12021-05-18 19:02:41,375: deebotozmo.ecovacsiotmq WARNING: 1621364561.257185| Error calling API https://portal-ww.ecouser.net/api/iot/devmanager.do?mid=XXXXXc&td=q&u=XXXXX&cv=1.67.3&t=a&av=1.3.1 StatusCode 502

And once i've this error in the logs

2021-05-19 01:39:04,283: deebotozmo.ecovacsiotmq ERROR: EcoVacsMQTT - error connecting with MQTT Return 5

    raise RuntimeError("EcoVacsMQTT - error connecting with MQTT Return {}".format(rc))
RuntimeError: EcoVacsMQTT - error connecting with MQTT Return 5

After restarting the docker container everything is working well again.

Does anybody else have recognized this problem or any solution on it?
