Anyone using USER SWITCHING plugin to manage users in multisite?

Hello All,

I have subdirectory setup here with wpmudev hosting.

I use USER SWITCHING plugin to manage my client's website instead using their credentials.

I've never had issues with this plugin until I started hosting this multisite here with wpmudev.

Now, every time I switch to my client's user account I get an error.

ERROR 502 - BAD GATEWAY

I get this error when I switch user either on a mapped subsite or unmapped subsite.

I use this plugin on my other multisite not hosted here and have no issues at all...Not sure what's going here???

I'm not getting an answer or at least a workaround fast enough? This is holding me back from marketing my services.
