Sounds like you might have some ISP introduced issues, however it will be good to revisit everything first just to confirm everything is setup and working properly. I would also advise switching back to 32400 for troubleshooting (or pick another non-standard port, using something like 443 may introduce it’s own issues since it is a common port used for other traffic).
Please read through Remote Access and Troubleshooting Remote Access support pages.
Then step through this guide: The Basics of Remote Access Troubleshooting
If you have been unable to get remote access working after you have completed all of the above (please be thorough and don’t skip any steps, or think you’ve already done all of this so you don’t need to bother), come back and we’ll dive into your setup.
