I hope I am doind this posting right. I did your tests and the reading was false and did not change. I bypassed the router, and no other firewalls appear to be active. What else can be doing this please. Thanks.
Get your friend to do this test:
Bug Report instructions & sample image If it's False then they're firewalled.
You should do the test also! I noticed your files are all red under Location column which suggests you're firewalled. Configure firewalls here:
