The problem with pages and members of mail.ru groups, you can't parse beyond the 25th page, what to do? 26 and next pages are loading, but there are no members?

Question

Parsing

PS (the script is ready, I can ask everything up to 25, in my group up to 64 pages, but there is no access from page 25 and so on!) I want to parse mailboxes of mail ru from groups, let's say there are 2 million members in the group, and there are only 25 pages in the participants, there are 20 participants in each page, there are no further participants but there are pages, that is, page 27 and further will be loaded but there are no lists of participants, my script is ready, it parses boxes but it is not allowed to go to 26 and so on, and take participants from there! in my group, there were 64 pages in the mail of 1.9 participants, I have access to them, I parsed all 64 pages, but again, that's not all, there is no further access, I'm not banned, etc., it's simply impossible! HOW TO SOLVE THE PROBLEM OF PAGES AND PARTICIPANTS IN MAIL.RU?
