Hey Mary,
I was just digging through the forums here and wanted to ask if there was any elaboration on the “weird things with Gmail’s servers”. We’ve been using a business Gmail account to send alarm notifications to various customers for quite some time now. For the most part, everything goes off without a hitch. Recently, I had a controller start returning 202 and -2104 errors. I ran through with Opto22 Support for quite awhile and we never really got anywhere. We ended up replacing the S1 and everything started working again, but it was quite a hassle. It’s a large customer site with a lot of floating point data to save.
Today, I’ve run into another customer where it appears to be similar. They’d been receiving their email alerts fine for quite some time. I was receiving the 202 error, and then after a restart of the controller, it’s switched to -2104.
Any ideas?
