If you are dealing with "server is offline" issues, then you may try using Cloudflare Warp 1.1.1.1 application software on Windows.
Try it and see whether the problem is solved.
Another way is to use VPN software. But Cloudflare Warp is a better option if you just want to use Imgbrd-grabber without hiding your IP. (Plus other typical unnecessary stuff related to VPN)
