[OpenSIPS-Users] ERROR:core:tcpconn_add_alias: alias already present and points to another connection

[Nabeel]

Hi,

I added a NAPTR record to my domain for TLS.  OpenSIPS resolves this
correctly and does the SRV lookup for the correct port, but then fails to
register with the following error.  Please advise how to fix.
