Invitation Mail Issue for New Users

Post by lebienaime » Fri Jun 26, 2015 2:01 am

Dear moderator, please feel free to edit my post as you see fit since it contains both error/bug report and question. It could be useful for the other members if what I did is correct.

Recently, I had a problem with registering new users.
The registered user didn't get the invitation to their mailbox.

My installation is OnlyOffice 8.5 on CentOS 7 with kernel version 3.10.0-229.4.2
The prerequisites have been met. No issue with the administrator registration, which is why I assumed that at a later date, user registration will be successful.

However, when I tried to invite new users to the portal, the email didn't reach the user's mailbox.

I browsed through the /var/log/onlyoffice and tried to find any entries relevant to that date and I found an interesting error in

2015-06-26 08:28:36,300 ERROR [1] ASC.TeamLabSvc - Can not start service NotifyServiceLauncher: MySql.Data.MySqlClient.MySqlException: Unable to connect to any of the specified MySQL hosts.

at MySql.Data.MySqlClient.MySqlPool.TryToGetDriver () [0x00000] in <filename unknown>:0

I figured that it must have something to do with the mysql connections and I tried my credentials on the mysql server . It worked properly.

What I did to fix this issue is to reconfigure by running the to enter the mysql connection parameters to onlyoffice.

Is it the correct way to fix this issue? Also, is there an alternative method to resolve this issue?

Try restarting onlyofficeNotify service, this may help. If it doesn't - running the once again is the only method.

I had the same error and after trying various approaches and a lot of searching I found out that there was a bug in mysql reported here: This bug is fixed in the 6.2.4 version of MySQL Connector/NET (see ... 6-2-4.html)
After all, the solution was installing the MySQL Connector/NET 6.2.4 and magically the mails started working well.
