Auto renew failed for our static and media subs and having a very difficult time renewing them or creating new CSR/SSL on server.

Anyone seen this error previously when trying to generate a cert and have any ideas?



Hi @TGS,

I haven’t seen this error before and I believe I wrote that particular line of code in Certbot, so I would be curious to get to the bottom of it if you’re interested in trying some more experiments.

You should be able to renew a specific certificate without triggering this particular line of code by:

① running certbot certificates and noting the name of the specific certificate that you want to renew

② running certbot certonly --force-renew --cert-name name-that-you-noted-before
