What issue do you have?

I use Minio S3 server. The first sync succeeds, however, when I do further syncs, also from another PC, the sync takes almost forever and eventually crashes with the error message "ERR_STREAM_WRITE_AFTER_END" and no further information. I see that S3 sync is still in beta, however, I do not want to use Nextcloud, as Joplin syncs very often (which is good) and this gives a lot of clutter in my Nextcloud "History" (which is bad cause I can then no longer simply determine when and where other files have been changed, as there are hundreds of entries of Joplin, doing its sync thing).
For this reason I wanted to use the S3.
Can I fix this with a change in the config of my S3 server, or is it possible somehow to adjust something in Joplin?
