Narrative:

During preflight preparation; a log item was noticed regarding the blanking out of the right tank fuel indicator and totalizer from a previous flight on [date]. The item was noted to be tested and reset. On climbout from ZZZZ; the right tank quantity and totalizer once again blanked. The crossing of the atlantic was normal; with the fuel burn and quantity tracked on the FMC. Approximately 1:30 from landing; the right tank quantity and totalizer came back but showed a fuel imbalance of more than 4;000 lbs. Between the left and right tanks. The fuel configuration EICAS message was displayed and the two first officers ran the appropriate checklist as I; (the captain); was on my scheduled rest break. I returned to the cockpit and the first officers informed me of the situation and what they had done with respect to the checklist. We discussed the fuel situation and we determined that we really didn't know our exact fuel quantity and location with the conflicting information from the totalizer and FMC generated fuel. A satcom call to dispatch and maintenance was initiated and it was determined that the best course of action was to [advise ATC] for unknown fuel quantity and receive priority handling to expedite our landing in ZZZ1; as we were only about 90 miles from ZZZ1. An uneventful landing was made in ZZZ1 and the aircraft was taxied to the gate.
