Thanks. We're overhauling the network code, which should fix this bug. We've restarted the seed peers so you should be able to connect in the mean time.

got the same issue here

[Douvi]

The app started back to connect

[pw96pw96pw96]

got the same issue here

[kaitoukidd]

here is the same error

[pw96pw96pw96]

The app could connect to peer now, though it still generated an error msg beforehand:

I guess it might just be timing issue: the depended service didn't start the first time, then it started, and thus connection is ok...

I notify when you open the app it's allwayse fail to get the connection. But after a time X it will successed connect

[UrbanSharon]

@pw96pw96pw96 - new binaries are available for download which should fix the issue you encountered

[UrbanSharon]

@Douvi this is not actually a bug or an error, it's just that the trace shouldn't be printing that. it's printed when a connection cant be established with a peer that's listed in the node's address list

[pw96pw96pw96]

@UrbanSharon - It will be helpful if instructions on how to build and run from source could be given. Anyway, thank you for fixing the issue.

[pw96pw96pw96]

@UrbanSharon I sent some Zen via the faucet into address 14eh93uk/Nfogl/NiyHVpwzxCXPz6Z8kv/CRMFVzaCr0=. But when I opened the wallet/portfolio, it says "Discovering peers: 0%" See screenshot. My node started via mono zen.exe -m is running fine.

[pw96pw96pw96]

@UrbanSharon After leaving the wallet open for a long time, it can show the balance now. I guess it was because the wallet was downloading all the blocks. Issue resolved. Thx.
