    Nginx Proxy Manager Certificate Key is not valid

    When adding custom SSL on Nginx Proxy Manager, i get following error.

    Upload failed: Certificate Key is not valid (Command failed: openssl ec -in /tmp/15dbf072-4022-aee94-0f88e4fb8d86/tmp -check -noout 2>&1 )

    Nginx Proxy Manager Custom SSL upload error

    I tried upgrading Nginx Proxy Manager to the latest version with the following commands

    cd ~/nginx-proxy-manager/
docker compose down
docker compose pull
docker compose up -d

    Even after the upgrade, this error persists.

    I checked logs for the docker container, but there were no errors.

    docker logs -f nginx-proxy-manager_app_1

    To fix this error, I edited the SSL key file.

    Find

    -----BEGIN PRIVATE KEY-----

    Replace with

    -----BEGIN RSA PRIVATE KEY-----

    Find

    -----END PRIVATE KEY-----

    Replace with

    -----END RSA PRIVATE KEY-----

    Now close the SSL upload dialogue and start over the custom SSL upload process. It will work.
