No connection to Nextcloud at <url> Operation canceled

I just want to confirm after enabling the bruteforce app and whitelist my router and isp modem IP address, everything start syncing again

Hi all,

I am having the similar issue but I am not at home right now to double check but I believe this is also something new.

I have Zorin (Ubuntu 16.04) running on the latest version of Nextcloud server. I have done nothing different and server had been running perfect for about 2 to 3 years. Now all of the sudden (I promise except updating Linux and I had done nothing). My nextcloud server will be offline and I cannot access it fro Linux or Web or Windows desktop. But if I reboot the linux server and it will start working again for a while and then stop.

Has anyone encounter the same thing? (this started in the last two weeks) and now I cannot connect to my cloud at all and sync all the changes as I go alone. Any suggestions would be greatly appreciated.

Thanks,

Brad

It seems like I have issue with apache2 server but it never happened until last two three weeks. Can someone please help me to read through this? Sorry I am using Windows at the moment (Linux).
