however, when I restart seafile on the backup server, no repositories are synced, I only see in seafile.log:
http-tx-mgr.c(514): libcurl failed to GET https://[backupserver]/seafhttp/server-sync/repo-list: Problem with the SSL CA cert (path? access rights?).
I have valid certificates installed on both the seafile server and the backup server. The webfrontend of both the server and the backup server work without problems.
When I check the URL that libcurl tries to access manually, I only get an empty page (no error message). On the seafile server I do not see anything, except an entry in the access.log of apache.
when I try manually with curl to access the repo-list I get (in the apache access.log)
[seafileserver]:443 130.60.156.11 - - [27/Mar/2017:16:10:54 +0200] “GET /seafhttp/server-sync/repo-list HTTP/1.1” 400 3386 “-” “curl/7.38.0”
