I have same issue on Dell Venue 8 Pro 5855 tablet with Dell Wireless 5809e (Sierra Wireless AirPrime EM7305; default SWI9X15C_05.05.58.00 firmware).
Please look into attached logs:
4:26 mbim-proxy and ModemManager proxy is started, then tablet was suspended
4:27 wakeup from suspended, connection is not established
4:28 second attempt to connect, also unsuccessful.
mbim-proxy and ModemManager termination and following restart allowed me to successfully establish connection again.
If my issue is different and I need to fill separate bugreport - please let me know.
