When I tried to add External Content Type via sp designer, I got following error

"business data connectivity metadata store is currently unavailable". sp2013.

I've tried many common solutions, any unfamiliar solutions please?

manage web app > service connectionss > BCS service application Services on server > BDC service > started

Someone said if this file C:\Windows\System32\inetsrv\config>ApplicationHost.Config has "< headerLimits > *** < / headerLimits >" this lines it might cause the error but our config file does not.

Please check if your server name has underscore '_'. If it has then rename it or connect via localhost

This does not work from SPD: http://server_name

This will work: http://localhost:9009
