I just backup my gitlab to a new disk partition, it took times to make all service run. but when i acces the webpage its still 502 error.
i got this error when open the page " : 185.220.101.4, server: 0.0.0.0:443
2021/03/09 09:25:23 [crit] 7211#0: *1368 SSL_do_handshake() failed (SSL: error:141CF06C:SSL routines:tls_parse_ctos_key_share:bad key share) while SSL handshaking, client: 165.227.203.110, server: 0.0.0.0:443 "
i have no idea why because the ssl is still active when i checked sslab.
@rg305 means that the error message you saw in your log file is not important, because the connection from 165.227.203.110 is not a legitimate connection and would not be expected to succeed. (Another way of saying that is that connections from this address always tend to fail this way, even on other people's sites unrelated to yours.) Because of that, the way that that connection failed isn't an indication of any important problem with your HTTPS configuration.
Looking at your site, the certificate and HTTPS setup is all working properly... the 502 error is coming from the GitLab software itself. Unfortunately, this forum isn't populated by GitLab experts and you'll need to ask the GitLab forum
for help in figuring out what's causing the 502 error message. Good luck!
