I have been running version update 0.13.0rc1 for a week or more. Port 8333 on my router was/is open. My PC (win.7) is up and running almost 24/7.

From yesterday morning, I've noticed that on my client wallet - the help > debug window > information shows that the number of Incoming connections stands on 0 (zero), and Outgoing connections stands on 8. which means that I have been unreachable from other nodes for more than a day.

When checking bitnodes.21.co tools, to check if my Bitcoin client is accepting incoming connections from other nodes - i get an unreachable result. My IP is statics, and doesn't change.

Any ideas why?

Check your local windows firewall. Make sure that it is allowing incoming and outgoing connections for Bitcoin Core and port 8333.

Make sure that the post is open for your local ip example 192.168.1.33 , it can change sometimes and then you would neee to update the ip in your router as well.

At least on my router it was like this many times that suddenly i got a new local ip and needed to update it in the router

I have been running full nodes for 2 years. No problem with the firewall, and no problem with the IP, which haven't been changed.

I've got unreachable to other nodes since yesterday. Before all was well, and nothing was changed on my PC, firewall, IP etc. I have also restarted my PC and router a couple of times, but still 0 (zero) Incomming connections on the network bebug window in my bitcoin client.

Can it be a bug on the v0.13.0rc1 ? Should I change back to client 0.12.1?

Is 8333 really open?
Did you perform a port  check test for that?What does www.canyouseeme.org (http://www.canyouseeme.org) say?

an update >> to make a long story short >> After checking the port and the rounter once again - I had to change the router to a NEW one. I just did so.
I plugged-in all the wires to the NEW router, and I after a few minutes I've got connected to the Internet and to the bitcoin network automatically!! even though I was using a NEW router, broght directly from the IT store (probably because of the Internet Provider's remote access).

I'd got immediatly connected to  http://178.62.20.190/ (http://178.62.20.190/) for a few seconds

after a few more seconds, I was connected to other nodes - with Incoming and Outgoing connections:

BTW - on site http://178.62.20.190/ - my IP status is NOT ACTIVE, while at the same time on https://bitnodes.21.co/ I am reachable and active. Why ?

What is this http://btcnodes.org/ full-nodes get connected to? the website writes >> © btcnodes.org 2014

It all depends on the site's crawler. If the site's crawler is connected to you, then it will say that your node is reachable. If it is not, then it will say that your node is not reachable even if you actually are.
