File History Service is not accessible

“I have Windows 10 on a desktop PC. I have been using File History to back up my data. Luckily today I checked the report and saw that no backups have been done since the 19th November. It is set to do backups every hour. I selected 'Run Now' to force a backup and got the message 'File History Service is not accessible'. I checked the external hard drive which holds the backups and it is up and running and I can view data on it using File Explorer. I have no idea what this message means nor what to do about it. Any suggestions? Thanks!”
