Impossible guild mission to do

The weekly task: Try the cooperative battle, it is currently impossible to perform. Our clan chose this weekly quest and once it is chosen it cannot be changed in any way, so you have that quest during that week as a must. The quest can only be done from 7:00 p.m. to 9:00 p.m. when the servers are down and it is literally impossible to queue. With several members of the clan trying to enter during those 3 hours several days, only a couple of lucky ones have been allowed to enter and be able to do it, for which the rest of us have been left halfway through the mission, leaving us without a reward and losing the experience of clan without us being able to do anything.

Given the impotence that all the members of the guild feel, what solution can be given to this problem or how can we be compensated for this loss of time queuing and, above all, losing the rewards that completing that mission gives?
