I’ve got some issues setting up the renewal process for a load balanced solution with 2 servers.
Generating the certificate with certbot (w/ Apache) was straight forward for one server but I was not able to do it for the other one. I was getting the error “Incorrect validation certificate for TLS-SNI-01 challenge.”.
To solve that, I just cloned the server who had the protocol set up and I removed the server that was causing trouble.
Now, I’ve got https “running”…that’s awesome but how can I handle the renewal aspect now ?
I cannot run the standard renewal process since I think it will fail for one of the two servers, won’t it ?
How can I solve my problem ?
