The same error happens with Duplicity on the command line, but it sucks less because resuming works.

When backing only a small folder (eg: ~/Documents) every thing works fine. However when trying to backup my whole home folder (/home/myusername) I get an "Invalid credentials" error after 5-10 min. The back up seems to start normally and my destination folder starts filling with "duplicity-full...difftar.gz" files, but eventually I get the Invalid Credentials error. lsb_release -d Fedora release 27 (Twenty Seven) rpm -q deja-dup duplicity deja-dup-37.1-1.fc27.x86_64 duplicity-0.7.16-1.fc27.x86_64 deja-dup.log attached. I cannot attach deja-dup.gsettings since i can only join 1 file. Will send if needed.
