Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Hello @pbumbray, welcome to the Let's Encrypt community.
crt.sh | mdm.uso.org shows issued certificate for test.mdm.uso.org on 2023-11-06.
However dev.mdm.uso.org last issued certificate was 2023-08-19, so yes that certificate needs to be renewed.
Also dev.mdm.uso.org access to Ports 80 & 443 are filtered.
