This is something related with the Jamod Library and the way is handled the tags. All tags are always watching if the connection is activated to be updated, so if someone deactivate a connection the tag will stop updating but while stop updating some polls are going to fail... Almost natural but awkward.

There is a bug ticket in the library forum: link

Thinking about changing Jamod by J2mod: j2mod

Jamod replaced successfully
