However.... My ISP seems to be a bit flaky at the moment and I get occasionally dropouts which resolve themselves. Cumulus seems to cope with this but sometimes when it's trying to open a new FTP connect I get a "Login authentication failed" message from the remote FTP server. This can happen for a few minutes and then it sorts itself out and connects just fine. What seems odd is that cumulus logging into the FTP site fails repeatedly but then after a few minutes suddenly connects and will start uploading again. If it (failed logons) happens too many times in quick succession the website/FTP hosting company have a firewall rule to block traffic from my IP address, which then requires me to open a support ticket to get resolved.
This issue has been happening for a few weeks now, before I was on 3089 so it's not specific to this version.
Here's an extract from my ftplog.txt before it starts connecting again (and when it does connect). The username shown in the ftp log is always correct (the one in the cumulus settings) but the password I cannot of course confirm as it's understandably hidden in the log file. It just seems odd that this authentication fails but then fixes itself again. This doesn't always happen, sometimes - I believe when my IP address changes as a result of a full reconnection to my ISP it seems that many multiple connections are attempted (which fail) and this then causes my web hosting provider to block the IP address of my ISP where Cumulus is running.

2020-08-12 13:18:26.792FTP[245]: Completed uploading realtime.txt to realtime.txt
A backup plan is to potentially use the Cumulus web command call a remote URL with lots of webtags which then 'recreates' the realtime.txt or similar file. I may need to resort to this for better reliability.
Any thoughts would be most welcome.
