Unable to use transport

Hi everybody !

Several weeks ago, i’ve setup Slack alerts. Then It worked.

Today i’ve seen no alerts since few days. I’ll want to test alert, but I’ve got an error “Test to slack failed - general error”.
I’ve tried to remote/add other alerts and type of alerts, same problem. I cannot remove this alert too.

On commande, i’ve got this

root@Librenms:/opt/librenms# /opt/librenms/scripts/test-alert.php -r 4 -d -h XXX
SQL[select * from `devices` where `hostname` = ? limit 1 ["XXX"] 0.29ms]

SQL[SELECT alerts.id, alerts.alerted, alerts.device_id, alerts.rule_id, alerts.state, alerts.note, alerts.info FROM alerts WHERE alerts.device_id = 4 && alerts.rule_id = 4 [] 0.14ms]

No active alert found, please check that you have the correct id.

An with ./validate.php

root@Librenms:/opt/librenms# ./validate.php

Hi,

For the test-alert.php script, the alert must be fired. I usually have a rule that always match, for example:
device_id = X AND macros.device_down = 0
That rule will be fired in the moment the device X is UP. Set the correct transport for that alert and then test-alert.php again.

Run test-transport.php too
