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.

Cert bundle was supplied via third party as a text file. It's been working for most visitors but some browsers (just recently) are returning 'insecure' warnings. When I check using 'whynopadlock' or similar services, reports indicate problems with Chain certs: 'You have an invalid or missing intermediate (bundle) certificate. This may not break your padlock on all browsers, but will on others. Please contact your SSL Vendor for assistance with this error"
Supplier says cert is good so there must be a config problem, software vendor says config is good so there must be a cert problem. I don't usually have to deal with SSL at this level so I'm really struggling with this! I've tried changing the order of the CA certs but it's not making any difference.
