When you say “can send recurring invoices manually using CLI or with old v4 cron tasks php artisan ninja:send-recurring” are you referring to invoices from v4 or v5?
Manually via CLI - when i go to var/www/invoiceninja and run command php artisan ninja:send-recurring ot when i put this command in cron. This command was used in v4? Now, in v5 we should use schedule:run
The version of the invoice ninja is v5.7.12-C124
Recurring invoices are only 2 weeks old, and are set to send daily (to test functionality)
In .env file there is QUEUE_CONNECTION set to sync
well, i also do not understand, i just tried it, as i found it in different discussion. It worked. But it is tmp fix. So i think that i will try to do clean install of the linux, db and invoice ninja,
