Errors using pacstrap on install

I’m installing Arch Linux for the first time. I didn’t encounter any problems during setup until I had to perform the actual installation with pacstrap. Here’s my input.

pacstrap /mnt base base-devel linux linux-firmware vim

What I get in return.

:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
error: failed retrieving file ‘online-repo.db’ from 192.168.1.156:8000 : Connection timed out after 10000 milliseconds.
error: failed to update online-repo. (download library error)
error: failed to synchronize all databases
==>ERROR: Failed to install packages to new root

I am able to ping archlinux.org and google.com without any issue, but not the ip mentioned in the error. I have heard that having timedate-ctl setup incorrectly can mess up sync, so I changed it to the correct time and timezone manually. I tried using reflector several times with different protocols and locations but I still get the same errors. I’m not sure what I’m doing wrong.
