Ssl initialisation fails and uploads fails


Im uploading from my android to my server about 600 files.
Most goes fine. But some files fail to upload and the notification i get is either ssl initialisation fails or upload faill.

Where can i find the log files to see why this errors occours and fix them?

Also is there a place to suggest a new feature? Because a pause uploads is a must to have feature.
Also an option to configure the behaviour with duplicates files. Etc overwrite allways…

Because its 600 files im using wifi. It takes time… Hours to be honest. I want to leave home and go somewhere so i want to pause the upload but i cant. So i stopped it.
When coming back and uploading again… Its duplicated the existing files instead of skipping them. So allllll from the begining…

Thanks for now
