Aircraft
We were on a normal approach to Runway XXR in ZZZ. When we attempted to select flaps 25; the FLAPS TE DISAGREE EICAS illuminated and the flaps stayed at 20. We went around from approximately 1;000 ft. AGL and I ran the non-normal procedure while the FO (First Officer) flew the aircraft as were vectored back for a visual approach to Runway XXR at ZZZ. We completed the non-normal checklist; sent a quick ACARS message to Dispatch; talked briefly to the flight attendants to tell them we were landing very soon; and made a flaps 20 landing. Per ZZZ Maintenance; we left the flaps at 20 and wrote up the malfunction at the gate.
B757 Captain reported a go-around was caused by the trailing edge flaps showing an asymmetry condition and stopped at 20 degrees. The Captain accepted vectors to rejoin the approach and made a successful landing.
