OpenBCI iHub fatal error listen EADDRINUSE 127.0.1:10996 [resolved]
Dreambuild
China
Hello guys, I just got my cyton board and started to test it using the newest 4.2.0 gui and 2.1.0 hub. The first time it worked well and got data streaming. However, in the following tests this error came with ''OpenbciHub fatal error listen EADDRINUSE 127.0.1:10996'' and the gui can't find the hub. Tried many times and ways but still turned out to be failure. Is there any way to solve it?
Comments
There is no bug here. This means that the Hub is already running, and attempts to use the same exact port for communications a second time.Hub has already been removed entirely for GUI 5.0. Please be patient as we refine this release.
For now, go into the Windows taskbar and close the OpenBCI Hub after closing the GUI, this error code means that it is running.
@retiutut Sorry to disturb you sir, I then tried to open the gui again without opening the hub individually, but the hub is still not connected. Does that mean I have to wait for another release?
Did you follow Richard's instructions to kill the old Hub, before restarting?

@wjcroft Yeah, already killed it with that. The problem is, when I restarted the hub, although the Error window doesn't exists anymore, the gui can still not find the hub. I guess it could be the problem of the environment of my laptop, since I copied my files on USB disk and ran it on my dad's 'anicant' laptop(there even no Bluetooth) and it successfully found the hub. Mine, however, only worked at the very first time.QAQ
Did you try rebooting your laptop?
@wjcroft Tried for many times. It never works. QAQ
Is this Windows 10, 64-bit processor?
@wjcroft Yes.
Are you running the 'standalone' GUI? Have you tried the Processing IDE version?

Have you used the Google Advanced Search button in the upper right column?

@wjcroft Really sorry for asking help again, but I really can't get though the problem with my processing, which is like this
I had follow the tutorial you provided and found no problem with the library, then this error came
The library
Any ideas on solving it?

@wjcroft No need to solve the previous question. The IDE had been successfully activated. But, as you can see:
The hub opened as gui was activated, but gui can still not find the hub

I finally found what's the problem with my gui. It was caused by my Vmess internet booster's protocol and the app I'm using seems to be blocking the 127.0.1:10996 port access. Still a lot of thanks for the help!
@wjcroft @retiutut
@Dreambuild Glad you got it to work. GUI v5 will not have this problem! Take care!
