Yes, the app on 9.18.3 and 9.19.0 are separate installations, I didn’t upgrade the app on 9.18.3. The app on 9.19.0 is a project which have been developed for a while and we tried to integrate Email Connector module. However, it didn’t work as expected. In addition, after I had seen your answer I created an empty project then integrated the module and it worked. I think there is a problem with integration to our exist project which is on 9.19.0. Unfortunately there are no logs or error outputs, we have just the error pop up “smtps”.
Lastly, I looked some similar issues that from Mendix forum, the most of similar issues were caused by .jar files collision. So we also tried to delete or change some .jar files as suggested in some posts but it didn’t work.
Can you briefly explain the issue?
Did you installed module in the app on 9.18.3 and it worked well and then you upgraded the same app to 9.19.0? Or you are talking about the separate installation into two different apps and it doesn’t work on 9.19.0? When i tested it on 9.20.0 and it worked perfectly fine for me, may be you retry once
