MySQL connection issues

Hi,

I have the report server setup and connected to a MySQL datasource.
Have found when trying to run a report for the first time, i always get the below error message, when i do a refresh it works fine.

Its a bigger issue for any (unattended) scheduled reports, as it fails to connect everytime.

Any advice?

Have replaced sensitive with XXXX

Re: MySQL connection issues

Hi hyjack,

for "config reload" you need to open your terminal (CTRL + ALT + T) https://reportserver.net/en/guides/admi … /Terminal/

You can alternatively just restart your tomcat.
