PM 2.5 sensor stoped working

After about 3 weeks now I am not getting anymore PM 2.5 data from my outdoor sensor unit. Everything else works fine. Any ideas of what that could be ? I tried resetting etc. but to no avail…

Hi, my sensor is being collocated with a reference station and after a reconnection of wi-fi it stopped registering PM, it shows that all components are measuring but PM2,5.
I was exploring in Analytics on the dashboard and it is measuring PM0.3, but not PM1, 2.5 adn 1o. I thougth it could be the measuring range since the values were very low a couple of days ago, but comparing the measures of the reference station the values were ranging 5 to 30 ug/m3, so even if the values are low, it should still be able to measure the highest concentrations.
I would appreciate some guidance and help! Thanks in advance.
I’m uploading some images:
