TLS initialization fails


When been connected via data (4g) and try to download a file, I get ssl initialazation fail error. This is not happening when I am connected via wifi.

Has anyone faced such an error?

  • If you have an error message, repeat this process to search for your error on the forum and internet.
  • If you do not find an answer, you are likely using the wrong keywords. Try simplifying your search on the forum and internet even more.
    • nextcloud php modules missing
