PushMessage Exception: Object reference not set to an instance of an object.

Getting this error message when attempting to send a Pushover message.

HS4

Is you Controller fully updated. Could you confirm what version of HS4 you are using, what version of the OS and Mono is installed.

I have just recently started seeing this. No message is sent. It started about 4 days ago. Note the app on the iPhone was updated recently to 3.7.2. I've updated HS4 and the Pushover plugin to the latest version and it still happens. Also when I updated the plugin I got this error message.

Unfortunately the OP didn’t reply to tell us if my suggestion actually worked. That’s nothing new on this forum. I’ve noticed your Mono version is reporting version 5.20 when in fact the latest version is at version 6.12. I’m fairly sure this is the source of your problem.

If you want to copy/paste the following commands into a terminal session I might have a better idea what your setup is. Could you copy/paste the output here.

uname -r

cat /etc/os-release

sudo mono --version

Depending on the results from these commands will determine what steps you need to take next.

Really don't know why this is happening, I haven't been into the system for weeks, it just runs. Anyway here you go....

Wow that setup really is old. Ubuntu 14.04 is no longer supported. The Linux kernel is ancient. Kernel 3.16 is way behind. I’m using Kernel 5.4 and as I mentioned your Mono version is at least one full release behind.

Leaving your system as is will only invite further errors going forward. I’m not familiar with the SEL but it reports x86 architecture so my best advice is to back up your system and follow the latest instructions for a HS4 Linux installation.

You won’t manually succeed in upgrading your system any further with the current OS in place and will probably end up breaking it.

I’d definitely start from scratch and restore your backup when your OS and HS4 is correctly installed.
