Check and make sure the chain file has been converted after the concatenated chain (.pem) file creation.

e.g: (Common command used)
openssl x509 -outform der -in chain.pem -out chain.crt

Resolution steps:
1. Re-generate the chain file key (.pem)
2. Rename the chain file from (.pem) to (.crt)
3. Import the chain file to Tableau Server (Configure SSL for External HTTP Traffic to and from Tableau Server)



Chain file is not properly encoded from .pem to .crt file.

Note: Tableau SSL certificate requirements
+ All certificates in the file must be x509 PEM-encoded and the file must have a .crt extension (not .pem).
