Magento2.2.5 Vendor subdomain problem Webkul B2bmarketplace

I have a problem with the subdomain module of the Webkul B2BMarketplace vendor. When I configure a wildcard on the server or local host of my website, I can enter the seller's subdomain, but when I want to perform a redirect within a subdomain, for example to display all the products or to check the evaluations, page 404 does not show up. It's weird because I can enter the main page of the subdomain, but when I want to open the sub-pages, I have 404. When I turn off the subdomains of the seller and my address URL is like "" everything works fine, it's a problem for subdomains and I can not fix that. Maybe someone has had a similar problem and can help me solve this problem? I will be grateful.
