Hi Admins, can you please help me, I change server with more powerfull new one (more CPU-s, memmory…) and import now broke everytime on new server. On old server all goes well, but now not. I have in my .csv file images on remote server, and some .pdf files too, but when import start on first item everything freeze …import only text (name, description, all attributes…) but images and pdf-s no.

In error log dont have nothing to point what is problem, so please, can you help me what php modules/plugins must be activated to work as it should be. I chack IP block on server, all is OK, remote server is not banned, when ping remote server – allso is OK, bat in some reason my import is not possible now ??
