I got an answer in the Vaultwarden support forum, trying to fix the upload sice. But I do not know how to do this changes in StartOS. Anyone??
You can track this feature request here - [feat] Allow Larger File Uploads · Issue #37 · Start9Labs/vaultwarden-wrapper · GitHub
Is there a way for me to change it myself Or do I need to wait for new code from an Start9 developer.
This code is all open source and you are free to modify the Vaultwarden wrapper and then sideload the customized
s9pk to your device. We do not support this however, so you are on your own if something goes wrong.
