Weird Server Reply error message

[wwatson]

Today we had some Scheduled workflows fail on Alteryx Server with the error Weird Server Reply.

It looks like this happened for workflows that had email outputs, either with output tools or event triggered emails (on completion or error).

The issue seems to be occurring sporadically.

Has anyone seen this error before and can explain what might cause it?

 Output tool email

 Event triggered email

Also getting the error when running the WF in designer.

The issue was with the SMTP mail server rather than Alteryx.

The error message could have been more helpful though.
