Since an hour ago, emClient says there’s an error connection with Gmail and the inbox doesn’t synch. Am I the only one having this problem? Could you please help me out?
I am using a PRO license and the app is up to date.
same issue here, just happened this morning
Glad to know I am not the only one then 
Hi eveyrone, same issue here on my em client. Do you know guys if Gmail or em Client has changed anything? Seems to be an SMTP authentication issue, but POP connection is lost quite often too.
Same issue

Same here again. Accepted Windows update last night, now eM not working for Gmail accounts but ok for Outlook accounts. Full Gmail access via web.
Don’t think it has something to do with Windows. I updated it yesterday morning and the Gmail account was working just fine until an hour ago.
I havent updated windows and still have issue so not that. I know Google have been doing some security updates, dont know if anything to do with that
Just for info. This is not an em client issue. I have the same issue using another mail client. Its a google caused issue
Yes, there is an issue at Google. And on a Friday. 
You can either contact them for assistance, or wait till they have resolved it.
In the mean time, you will need to use your webmail interface.
You will find the same issue with any application connecting to Google with IMAP.

Google was completely down an hour ago. Google and Gmail are working again when you go to their website. But looks like IMAP still has issues.
I have the same problem, presumably it’s a google issue and will be resolved in due course.
[XMPP]Cannot access a disposed object.
Object name: ‘SslStream’. is what I am getting
Issue is improving on my end, not disconnects for few minutes and email sync is ok
Please see:
