Occasional webdav errors

  • Hi,

    From time to time, but not every time (based on a daily backup), sending the backup to a webdav volume results in an error.
    Most of the time it will be ‘<>Error Message: Unauthorized’ but I have also occasionally seen ‘<>Error Message: OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104’.

    I’ve searched the log, can’t find anything revealing.

    Here’s the log of an interactive attempt this morning.

    The question is: what can I do to avoid these errors? Sometimes the transfer is done, others not.

    Hello,

    That seems to be a SSL error, I suggest you to check with your hosting company and see if they can assist with.

    You mean a SSL error could occur sometimes but not all the time?

    Hello,

    Sometimes, yes, your website server or remote service may throw errors if something wrong.

    Alright, I think you’re right and the issue is probably related to some instability on the webdav server side.

    To say that, I’ve been doing some tests from my computer in order to isolate the client part from WP and the plugin, cause I felt the problem was on the server side.

    Whether I connected to the webdav server using https (my browser) or davs (my file explorer), I’ve noticed anomalies in the form of link breaks when browsing the tree structure on the server.

    So now, what I’m trying to do is reduce the number of pieces of the backup to be sent by webdav, from splits of 250MB to 2048MB (should be one piece), since I guess this would be just one send, so just one connection between WP/Xcloner and the webdav server, and maybe it won’t fail during the transfer, holding the “session” while it is transfering data.

    Let’s see how it’ll work in the few days acoming.

    If it works then… it’s OK and eventually I’ll hook up with the pCloud guys.
