Thanks for your assistance. I could not figure out how to reset API so I did a reset of Firefox which cleared the loading page but moved me to an "Application initialization issues" page showing the API connection as wss://bitshares.openledger.infor/ws and that is not connected. hitting the retry button temporarily moves me to the loading page and then returns as not connected. Error msg showing both connections was interupted while loading and that Firefox cannot establish a connection to the server.
This appears to be a problem with my computer and I guess I need to take it to a technician to work thru it.
