Stuck at 75%

Ok so this is the second time I’ve tried to use this plugin to migrate a site. Each site is on a completely separate server. Every time I attempt to complete the import, the upload process freezes. Changed php.ini to the following, which allowed me to start the upload process. What else should I try to get this to work?

max_execution_time 6000

max_input_time 6000

max_input_vars 1000

memory_limit 2000M

post_max_size 2000M

upload_max_filesize 2000M
