No counterparty servers are currently available

For more than two hours now I cannot connect to https://counterwallet.io/

Error message says:
No counterparty servers are currently available. Please try again later. ERROR: The server is not fully caught up to the blockchain. Please logout and try later. (Most likely this message is due to the server being updated.)

Do I just need to wait and try more?

This happens due to blockchain reorganizations.

All Counterwallet servers (because they use the same Bitcoin blockchain) are affected by this, but faster servers recover (rescan reorganized blockchain blocks) faster.

https://counterwallet.coindaddy.io/ is faster (compared to https://counterwallet.io) and it used to catch up within 30-45 mins of each reorg, so you can try there or be back to the “official” server in 60-90 mins.
