ERROR: failed to find registered SSL endpoint for '' ATS 6.1.1 Built against RHEL-openssl 1.0.1e-fips
Has anyone identified any legacy/broken clients out in the wild that may be responsible for causing these errors ? I cant seem to generate the same error using openssl: openssl s_client -connect ip:port -nextprotoneg '' If I pass an empty list, ATS just returns a list of supported protocols and closes the TLS connection. Which is per spec(if i read correctly). The request must be flawed some other way for ATS to generate this error. I can't run debug or packet capture on these machines since they are in production The error seems somewhat innocent.. I am guessing what I may find is that these errors are caused by some broken/incomplete client/TLS implementation. I am leaning towards this being something amiss with early implementations of boringssl. However, while I am testing some older clients I am putting this out to the community. Maybe someone here has already identified some broken clients or identified a general area causing these errors to generate. Thanks!
