Daily Update Broke Poller

Help

Hi everyone,

Since last daily update on midnight (local time) the poller stopped working.

Anyone else seeing this behavior?

Regards,

My poller is crazy… sometimes all ok… and some time goes all wrong:

My Poller stopped working right after the update this morning. Is is possible to rollback the update?

I was seeing the same problem this morning - but manually ran the daily update script again and it looks like there’s a new patch already if the version numbering is anything to go by. No longer getting any errors about being unable to import the .env.

I tried running update again and it seems to have fixed my problems. My charts are populating once again…

Indeed, I ran the update script again and the poller is now working as usual on the newest version.
