Synchronization Failed

[reignbeau]

I updated and downloaded the blockchain successfully but couldn't mine. I made changes these changes to my router.

UPnP is on
Port Forwarding is on.

This resulted in the following errors and I could no longer import blocks. I am currently using the following settings.

build/bin/geth -mine -minerthreads 4 -maxpeers 16 -nat any

and get the following errors.

And then new problem just now while writing this, I started getting this message in addition to others. I assume this means that my node is being blocked due to being buggy.

I0510 11:50:12.784277 2152 sync.go:103] Synchronisation failed: no peers available or all peers tried for block download process peers avaialable = 11. total peers = 13. hashes needed = 0

I've tested and gotten the same error on both my Windows install as well as Ubuntu install. I'm going to tinker around with my Router some more and keep you updated.

Perhaps related to #868
What version of geth are you running?

Running Olympic release.

Geth -updatedb

seems to have fixed the synchronization failure, but still can't mine yet.
