The last commited block is always 12201101. Why Sandbox no longer able to synchronize with the network?
I don’t see this behaviour - it’s working fine for me
./sandbox status
algod - goal node status

yes but it’s not working for me, do you how to resolve?
After entering in the sandbox via ./sandbox enter algod, can you copy-paste between triple backquotes ``` the output of:
tail -n 20 node.log
carpenter -D -cat
(for the latter just copy the last 20 lines)
Ha! I’m sorry, I was checking that there was no issue with the nightly build or some other software issue 
Not very helpful for resolving your issue though.
Like Fabrice said, if you could grab those logs, and also re-run the ./sandbox status after its been up for and paste the result here.
