No subject alternative DNS name issue

Just run into this weird issue, but we did not find any githubstatus reporting, so how should we proceed on it? Thanks!

Error log:

:::: ERRORS
	Server access error at url https://maven.pkg.github.com/<jar-path>/<jar-name>.jar (javax.net.ssl.SSLHandshakeException: No subject alternative DNS name matching maven.pkg.github.com found.)
