问题
Long time back I have created a composer network by using composer version 0.19.0. Now when I am trying to ping the network using following command getting this error.
composer network ping --card admin@tutorial-network
output :Error: Error trying to ping. Error: 2 UNKNOWN: identity expired
Please help me how to resolve this issue.
回答1:
Do you have any other identities registered (and thus have cards in your card store) with your business network which haven't expired ? If you don't then you are locked out of your business network. If you do but they don't have the appropriate ACLS to perform things like identity management (composer identity issue/bind etc) then so long as you have a card that doesn't have an expired identity that can perform install/upgrade you could upgrade your business network to provide required ACLs for that participant to be able to do identity management.

I had same issue today and solved like below.
First you need to delete that card using this command.
composer card delete
Then you can add a new card. (You have a .bna file at the same directory) Use this command below for importing new card.
composer card import --file networkadmin.card
You can ping successfully.
composer network ping --card admin@cardName
I hope this will solve your problem. Then you can start the rest server with below code.
composer-rest-server
