Time to dabble on the technology end and this time no more old time Java, but more to NodeJS. Those looking for the answer to solve the following RFC 6066 issue.
[DEP0123] DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066. This will be ignored in a future version.
It looks all gibberish but after reading through the warning, it is actually very simple. It means that IP address is not permitted but to use the ServerName instead. Wait, hold up, but shouldn’t that be okay? For those that hit this issue, here are some things you might have to check on your NodeJS version.
Open up the command prompt or your terminal and type this
node -v
I believe that your current version would be node v12.xx.x which would create this warning and hence you are not able to connect to the server mentioned.
Where did I learn NodeJS?
Everything now can be learnt online. There are multiple online platforms to perform these and the one I have been using was Udemy. If you would like to learn too, you can sign up too. Click the banner below or the one on the right to learn indefinitely.

Solution To Solve IP Address not permitted by RFC 6066
Upgrade NodeJS
Upgrade your NodeJS version into the newest stable release. At time of writing, this is at version 15 which should resolve this issue as I believe the IP address is now ignored in future version.
Use ServerName on Current NodeJS Version
Rather than use the IP address, use the current servername instead and this issue will be resolved. NodeJS is just that simple.
Voila. Problem is now solved.
Simple – Ha! What happens if you only have an ip, and no DNS / Servername? Then how are you supposed to connect?!
As mentioned, it’s not possible with older version. Updating NodeJS to version 15 is the only solution.
