Hi Paul,

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1380897593: Fetching https://get.typo3.org/v1/api/major/9 failed. Maybe this instance can not connect to the remote system properly.

I assume that you are affected by Let’s Encrypt’s DST Root CA X3 certificate expiration (details), most probably due to an outdated openssl version on your webserver.

To drill down this issue, please check

curl --verbose --output /dev/null https://get.typo3.org/
  • openssl version
openssl version
  • openssl connection
openssl s_client -connect get.typo3.org:443

and let us know it’s output.
