Transaction history says "unverified" and "-1 confirmation"?

[runam0k]

Sure I read about this already but I can't find the thread.

I set up an offline wallet on a Raspberry Pi - super easy, so far so good - and a read only copy on my online PC.

I sent coins to the offline wallet which, according to blockchain.info, went find (13 confirms and counting). However, in the Electrum client (online PC), the same transaction is reported as "unverified" with "-1 confirmation".

Is that normal / a bug?

Select a different server manually, then restart the client and enable auto-connect again.
