I have 4 pac R1 units that are set up to email on alarm conditions via a gmail account. This has been working for me for a few years now. I used the sample code from the opto22 site and tweaked it to suit, worked wonderfully! As of october2015 this has failed to work and I get a -11 error anytime an attempt is made. I have setup a controller outside of our company network at my home to eliminate the possibility of network issues unique to our company network, the same thing happens at both sites.
I have taken the step to weaken security on the gmail account to try and eliminate authentication issues. I am pretty much flummoxed as of now . firmware is r9.1b
Does anybody have any ideas on what could have occurred?
