I’m hosting a small number of domains on my Windows 10 “webserver”. I’ve moved them from an old system, using the existing letsencrypt certificates, which are still valid. After the movement, I tried to receive new certificates with Certifytheweb, to ensure, that all is working as expected.
Unfortunately, I got a key mismatch error on all but one domain. See screenshot attached. I tried to use a different mailaddress and have restartet Certifytheweb, but no success. The test feature from Certifytheweb for all domains results in a success.
Any idea what is going wrong?
