HTTP client stops responding
I'm using ebusd with E-Service eBus Coupler USB and collecting data from HTTP client with telegraf. But after some time telegraf either starts to report stale data or stops collecting data at all.
The following is logged by telegraf:
Oct 14 17:18:32 vaillant telegraf[2890]: 2021-10-14T14:18:32Z E! [inputs.http] Error in plugin: [url=http://localhost:8080/data/bai?maxage=120]: Get "http://localhost:8080/data/bai?maxage=120": context deadline exceeded (Client.Timeout exceeded while awaiting headers)
and by ebusd:
2021-10-14 18:00:31.301 [update error] unable to parse read bai Status16 from 3108b5040116 / 00: ERR: invalid position
2021-10-14 18:00:31.468 [update error] unable to parse read bai Status from 3108b5110103 / 00: ERR: invalid position
2021-10-14 18:00:41.127 [bus error] prepare message part 0: ERR: end of input reached
2021-10-14 18:00:50.890 [bus error] prepare message part 0: ERR: end of input reached
Interesting enough -- once stopped, data collection via HTTP resumes back (but not for long) if I run any ebusctl command, i.e. ebusctl i.
Could you please advise if this behavior is expected or is there anything I can do about it? Thank you.

after what time does this come up?
I wasn't able to find any pattern. This may come up after 20-30 minutes or 3-4 hours after restart. I'm gathering data every 3 minutes and Telegraf is installed on the same host with ebusd (if that matters).
