Narrative:

I was performing a closed-pattern training flight with a student pilot at ZZZ. I was in contact with tower.on the final leg; tower advised cleared to land xxr; land long for X-2 (taxiway). Student pilot correctly read back instruction and landed between the approach end of xxr and taxiway X-3. Upon landing; tower instructed 'exit at X-3'; which the student pilot read back correctly. Student pilot applied heavy braking to exit at X-3 as instructed.aircraft Y was holding short of xxr at X-3; and as our aircraft began exiting on X-3 it became clear that there would not be enough space to exit at X-3. At this time; tower instructed our aircraft to 'stop right there'; which we did. Tower instructed aircraft Z on final for xxr to go around; and instructed us to taxi to X-2 and exit the runway. I read back the instruction; and affirmed that we had been instructed to exit at X-3. Tower controller disagreed and reprimanded student pilot and instructor. In summary; tower provided incorrect instructions to aircraft which were properly read back followed; causing an aircraft on short final for landing to go-around; and for two aircraft on the ground to become close to each other.
