Specific ports not opening

My YunoHost server

Hardware: Raspberry Pi at home.
YunoHost version: 4.1.7.2
I have access to my server : Through the webadmin and direct access via keyboard/screen.
Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: No.

Description of my issue

Hello, l am setting up a YunoHost server for the first time and I have encountered a specific error. My ports did not work on the first time setup so l set up port forwarding for all them using my ISP website (I use TP-Link and it is called Virtual Servers in that if this helps). I set up port forwarding for all of them and 4 began working, however 4 have not no matter what l do. I have remade the virtual servers, reloaded the firewall several times and even done a reinstall of YunoHost, but the results are still exactly the same. I do not think my ISP limits my ports because l have looked in the YunoHost page for that and nothing shows up for Oceania. My only idea is that it might be because it says my IP is blacklisted on Invaluement, but when l go to the website to appeal my blacklist it says my domain and IP both aren’t blacklisted, which is also quite confusing. If anybody can help me out with this, l would appreciate it very much. Thank you.

Here are the error messages.

Edit:

Nevermind, l am stupid and was looking on the wrong website for my port settings (modem settings and not ISP settings?). I fixed it by going onto my ISP’s site and turning off port blocking. Thanks to rungeard for commenting.

Hi !

This issue is only related to mail which could be then considered as spam, but it has nothing to do with port forwarding.

Regarding port forwarding, it seems that you have done everything correctly in theory. Maybe to help you a bit can you elaborate on

and maybe also which is your ISP ?
