They both make sense. The better one is "I got disconnected."

Both are fine. "I got disconnected" might sound more American -- whether that is good or bad is up to you!

I was disconnected or I got disconnected? Both sentences are good but it depends on how you have been disconnected. If the power goes out and your computer is turned off by itself, then you used 'I was disconnected'. Whereas, if you shut down the computer by yourself and in that case, you used 'I got disconneted'.

I prefer to use " I was disconnected."
