[DEP0123] DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066

I am using tedious 6.6.2 in one of my projects, it is a GCP cloud function environment, with nodejs 10, and i am getting a warning related to tedious: "severity":"ERROR","message":"(node:6720) [DEP0123] DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066. This will be ignored in a future version.\n at Object.connect (_tls_wrap.js:1619:15)\n at MessageIO.startTls

Also when i do a node --trace-deprecation it shows another warning: tedious deprecated The default value for config.options.enableArithAbortwill change fromfalsetotruein the next major version oftedious. Set the value to trueorfalse explicitly to silence this message. What can/should i do about these warnings?

Change

Encrypt=true

to

Encrypt=false

in your code

for example

sql.connect('Server=localhost,1433;Database=database;User Id=username;Password=password;Encrypt=false')

I think I found the official explanation from RFC 6066, which states:

Currently, the only server names supported are DNS hostnames;
...
Literal IPv4 and IPv6 addresses are not permitted in "HostName".

  It is RECOMMENDED that clients include an extension of type
   "server_name" in the client hello whenever they locate a server by a
   supported name type.

   A server that receives a client hello containing the "server_name"
   extension MAY use the information contained in the extension to guide
   its selection of an appropriate certificate to return to the client,
   and/or other aspects of security policy.

Sorry you’re running into this issue, but I don’t think this is an error in tedious driver as I’ve also seen other people post this same error warning when connecting to other databases like MongoDB. I’m not sure how to solve this issue, but I hope I provided some helpful links for further guidance.

Closing this for now!
