I'm facing this error here at tag 8 and 9 respectively... any guidance is appreciated

@Anas-Nabulsi Would you be able to privately share a similar version of your certificate/key with some obfuscated information? (but generally the same kind of characters)

Please make sure these are never used on production on your end.

@obahareth , you actually pointed me to the right direction. It was an incorrect certificate and key. After I ensured they are correct, it worked perfectly. Thanks a lot.
