Stuck with status "Connecting"

[pate313373]

Hi, thank you for your node!

I'm receiving mails via mail-in node directly connected to the email action node.
I can confirm, that I receive messages and read them via debug node, but the email node is stuck with green status "Connecting" and not sending any further message.

I've double checked the node configuration, of course. Any help is most appreciated.

Best reards
