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.
Your certs are coming from the "Let's Encrypt Staging Server" You will need to use the "production server" to acquire your certs that will work for you.
Will you share the command used to obtain the certs? I am relatively certain it will reveal the issue and help us resolve this problem quickly.
Hope this helps.
OK thanks.. I dont use kubernetes and am not familiar with it's functions. AN expert volunteer here may be able to help you. I found this with a quick search...
