Connect to a captive portal using multiple vwlan

Hello!
I’m from Cuba and here we have only a ISP (ETECSA) who sell internet using a captive portal in parks using wireless AP. I have a SXT SQ5 ac with multiple vwlan connected to a park’s AP, each vwlan’s behavior act like an independient device connected to the Huawei AP. So my problem is: a month ago I could connect with any problem to the ISP’s APs, but now is like the APs cant handle more station or drop my device. Here I have a log output for been mor specific. Thanks in advance for any help!
