Connection resets to Maven Central

I’m getting connection resets to maven central (not getting these from travis on the same project). I’ve checked sonatype status, which seems green. Are there any issues going on? Are there workarounds (ex I might try using google mirror until this resolves)

Ex from but also in similar builds from different projects:
