Invalid Intermediate Chain. Please remove any whitespace.

5
Hello,   When adding a custom domain, I’m uploading a certificate signed by my CA. In the past, we’ve uploaded the certificate bundle as the Intermediate Chain. I can look at past certificates, and see we’ve used cert bundles going back 3 years.   Today, I went to update a Mendix app’s SSL/TLS cert for 2022-2023 and I received the error “Invalid Intermediate Chain. Please remove any whitespace.” I double checked my cert and there is no extra whitespacing. Has anyone ran into this issue?

Yeah this started happening to me as well. You can upload the the upper part of the intermediate chain and its still valid but yeah; that's not how it's supposed to work. Nor would I advise it.

I had the same error, and had to delete a newline at the end of the certificate. If you ctrl a, you can see if there is a newline at  the end.
