Aircraft X departing ZZZ the left main gear would not retract. We had the 'GEAR DISAGREE' and 'GEAR DOOR' EICAS messages along with the amber 'DOORS'; 'GEAR'  and green left main gear down and locked light. We advised ATC we had a gear issue and wanted to level off at 4;000 feet as to avoid terrain in the area. ATC offered vectors to stay in the area and we accepted. ATC then had us climb to 5;000 feet to avoid terrain in the area they were vectoring us into. We then ran the normal checklist and then the GEAR DISAGREE and GEAR DOOR abnormal checklist. Neither of which fixed the issue. Then we contacted maintenance through AIRINC. We discussed the issue with them and maintenance asked if we cycled the gear down and back up. I told them no because our procedures did not direct us to do that. Maintenance then directed us to cycle the gear to see if the left main would retract. We did as directed but the same indications remained illuminated.  At this point I told maintenance we were going to request priority and land back in ZZZ. We had burned off enough fuel as to not have to land over weight. I am sure the left main was still down because I could hear rumbling and feel a vibration coming from the gear and gear doors.  We requested priority with ATC; ran the checklists and landed on runway XX without incident. On thing I would like to add is that the AIRINC frequency was very broken up and weak. Having a phone onboard would have been very helpful. I would also like to add that the FO did a wonderful job in this incident. He was very professional and precise.
On the morning of date around XA:10z; the crew from Aircraft X; (ZZZ-ZZZ1) called in AIRINC to inform Dispatch and Maintenance Control they were having problems with their landing gear. When they went to retract the landing gear the left main gear was indicating yellow light when gear handle up. I told them to follow their QRH. They responded and said they were and were returning back to ZZZ. They asked if there was anything else they could do; again responded to follow their QRH. They said they were and again asked if there was anything else we would like them to do. I told them if it was possible and if they OK with it to try and cycle the gear one more time to see what it was doing. They responded OK and proceeded to cycle gear. Same problem repeated. They then returned to ZZZ; they landed without incident.
Captain reported left hand main gear did not retract on takeoff. Captain elected to request priority handling and an air turn back to make a precautionary landing.
