I use unencrypted Blitz and just last night I started getting really slow upload speeds, like 400 Kbps. I have run Speedtest and the RClone speed test built into PGBlitz and both show no issues. For example, the Rclone speed test uploaded a 4 GB file in just over a minute. But I have a TV episode uploading that is 4 GB and it is taking 3 hours to upload. Is there anything I can do to check why this is happening?
