Android client login bitwarden, HTTPS cert problem

SOLVED

  • ref: Android client using self-signed Let’s Encrypt for self-hosting
  1. Something changed
    Something has changed upon recent Android updates as indeed previously worked by transferring own generated Certificates to Android… but no longer.

There are wrong information out-there, that says that Android not further accepting self-signed certs by Let’s Encrypt… this is myth and not true (more on this underneath).

  1. Anchor error and “need Private Key”
    Upon transferring self-signed certs by Let’s Encrypt to Android, one may face Anchor error or “need Private Key” pop-up message.

There are wrong information out-there, that says that Android not further accepting PEM certs format, and that must be converted to DER or P12… another myth and not true. Android still accepting “proper” certificates by Let’s Encrypt, either PEM or DER.

  1. Solution
    Go to Let’s Encrypt certificates webpage and download an INTERMEDIATE Certificate (PEM or DER). There are different versions, but any should work.
