    since this morning I have found 5 domain names with following error message (LetsEncrypt certs)

    Code
    1. SSL certificate is not valid: C = US, O = Internet Security Research Group, CN = ISRG Root X1 error 2 at 2 depth lookup: unable to get issuer certificate


    does anyone have an idea how it can be solved?

    Edited 2 times, last by fulltilt ().

  • It's a let's encrypt issue. The plugin need to be fixed for certbot r3. I hope it will come out soon. All my domains are affected too :(

  • debug output

  • certs are created under /etc/letsencrypt/* now I have added by hand the certs into the controlpanel SSL cert section

    same error message:


    SSL certificate is not valid: C = US, O = Internet Security Research Group, CN = ISRG Root X1 error 2 at 2 depth lookup: unable to get issuer certificate


    which shows that something does not work with the letsencrypt validation procedure, a purchased positive ssl certificate works

  • I don't know it it will work or not, but maybe mentioning Nuxwin here will make it fixed faster. :-)


    For me it's not working as well, changing LE source to development is not fixing the issue.
