We have a large number of remote devices which have stopped communicating. Since they are not communicating, we cannot send them any updates.
curl: (51) Cert verify failed: BADCERT_EXPIRED
Our only option would be to either find a cert provider that still supports X1 or find a way to add X1 support on our server.
Is there a way to add support for X1 on the server just long enough to recover the devices?
I don't know enough about SSL to know how I could do this. Perhaps an intermediate file with the other letsencrypt files that the apache server is using?
