I have been getting this thing:
If you have this issue, the best workaround is to Wayback Machine.
Works for me. Are you using a suspect network connection?
No. I don’t know why it doesn’t work.
Problem is solved.
next time test with:
openssl s_client -host gmic.eu -connect gmic.eu:https < /dev/null | openssl x509 -noout -text
The important bit of the output:
X509v3 Subject Alternative Name:
DNS:cimg.eu, DNS:gmic.eu, DNS:www.cimg.eu, DNS:www.gmic.eu
The complete output for me looks like this:
depth=2 C = US, O = Internet Security Research Group, CN = ISRG Root X1
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = R3
verify return:1
depth=0 CN = gmic.eu
verify return:1
