Environment

Usage Meter 4.8

Cause

• The error C0410CD4977F0000:error:0A00010B:SSL routines:ssl3_get_record:wrong version number:ssl/record/ssl3_record.c:354: indicates that the proxy server is not accepting SSL/TLS connections on this port.
• This happens when proxy server uses a different protocol than Usage Meter, like SOCKS (Socket Secure).

Resolution

• Usage Meter does not support SOCKS proxy. Only HTTP and HTTPS proxy is supported.
