Issue with upgrading modules

[movieseals]

TB is asking my to upgrade modules but when I try to, I get this error:

4 errors

1. Failed to download module "coreupdater" from api server
2. Failed to download module "mailalerts" from api server
3. Failed to download module "statsmodule" from api server
4. Failed to download module "tbphpmailer" from api server

That will be some 'security' measure installed on your server - firewall, antivirus, or something similar that blocks your server from downloading zip file.

Or maybe write permissions for /modules/ directory

Fixed permissions, disabled firewalld, disabled csf, still same issue.  Is there a port I should open to allow connection to the api?

list of modules is fetched from https://api.thirtybees.com/updates/modules/all.json

Modules zip files locations are listed in the json file. Usually it's github, but some premium modules have different location.
