I'm using ejabberd for communications. While sending files using xmpp client (f.e. gajim) occurs certificate error:
Upload_file
CERTIFICATE_VERIFY_FAILED
Certificate exists, tried to uncomment no_sslv3 in conf - same result. What can cause it? In addition any info, about how file transfering works (can NAT effect on ssl) and is it possible to check if cert is correct would be great.
