Has anyone come across something like this: sometimes when I try to login to my app on web client, it will take my login credentials, then in the top right it will sit on "Loading..." for a few seconds before changing to "Error calling server...". It is very sporadic and doesn't happen at a specific time of day, just random. The silly part is that it will not leave the login form, but if I close the browser and reopen to the solution, it will open it as if I had just logged in.
Any clues?
