I am having difficulties getting a Letsencrypt certificate for a site I deleted and recreated under a different ISPConfig client. I realize now I probably should just had change the client for tge site but that is heinsight now. I noticed if I delete a site that had a LE cert, the LE cert files persist. Is is the expected/by-design behaviour? Besides the LE files not being deleted, I can't generate a new LE cert for the same site domain under the new client id. The LE error log says DXDOMAIN could not find an A record for the domain but of course the A record is there as I did not delete it from DNS: nslookup returns the A record fine. Any pointers?
