Any idea how to interpret these results?

Every time I run the test I get successful connections to a different set of people. Perhaps due to symmetric NAT issue?

Yep, me too. Just looking at the larger stats showing a 50% and slowly declining success rate. May be great, may be not so great. At least we can all do something to help.

Yesterday connections totally failed and today when my ISP gave me a public ipv4 adress we have lift off, connecting UDP, failing TCP, sometimes successful TCP connections. @ustulation
@JPL , Saw that you responded to some people with maybe similar problem to what I had, don’t know if you saw the solution I found, so I tag in this post.

Did some late night research and found what might be the problem. Due to shortage of ipv4 adresses my ISP probably uses CGN/CGNat and gave me a private adress. Basically it is like being behind two NAT’s with my router connecting to the ISP’s router and then to the internet.
Found a link which describes the problem.

Thanks. This is a naive question, but wouldn’t a work around for a symmetric NAT situation include just running a random port scan on the targeted peer? There’s only 65535 ports so “eventually” we would connect, no?

@jeremyjpj0916 we ended up connected! Along with man many others. Great stuff. Is it beneficial to re-run the test??
Edit: Rerunning just now and way more successful connections out of the gate! @Josh you’re in there! I literally can’t get over this.

I hope all the devs involved in this know how great a job they have done and are doing here. It is tough, ground breaking, work that can probably never be appreciated enough. You owe yourselves a big slap on the back and a a glass of your favourite beverage!

For me, using MAC OS, the client crashes with WARN after a couple of hours or less. Before this, however, successful connections win the day! cheers!

@MaidSafeMan How’ve long ago did you start? Remember it checks for new connections every 10 seconds and then makes new attempts so over the course of an hour or more you can get quite a few more peers. Running the test a second time after it said it was completed in the terminal gave me many more successful connections straight away for whatever reason.

I got about 30/70 success/failure with our house wifi.
Now I switched to my phones wifi hotspot and I also got only 2 connections. Then I restarted the test, and got again 2, but they were different 2. Also all the failed ones seems to be in different order.
I don’t have any idea what all this means, just reporting the behaviour.
Just out of interest, who is your phone carrier and where are you located approximately? I’m on Telia south of Porvoo. I’m now connecting using Pia VPN via Sweden and it’s working pretty well - maybe around 60 % success rate.
