Can't access my admin panel - Connection Refused

[Runtime]

Hi There, I setup two different instances of MIAB over two years ago. They both have been working fine until one just stopped working and I realised today. I cannot access box.mowash.app/admin at all. I have restarted the server and even reinstalled MIAB? Any idea what could be wrong?

The page seems to be loading.

Are you able to access from a different IP address?

Thank you very much for this. After hours of struggling, I just turned off my wifi and used data connection from my phone and it works. What is strange is that I was able to access the other email server with the same connection.

Thank you so much

Perhaps try a different device from the same IP address. Maybe you’ve somehow tripped fail2ban?

I can definitely confirm that it works from a different network but fails from my home network. Is it maybe blacklisted somewhere somehow? My home network that is?

A different device on the same IP also fails but if I connect it to a different network it works.

It seems likely your IP address is banned. You first should try and figure out why it was banned. Here is a tip from a different thread:

@murgero

A few reasons:

1. Your computer or mobile device is compromised and someone is using it to brute force or otherwise try to access your email.
2. A device on your network (might not even be yours) could have malicous intent in the form of infection or local hacker (in the case of wireless with low-security like WEP or small password.)
3. You have an old device on your network still using an older password, and as it tried to sync to your remote MIAB server, it gets your IP blacklisted.

Just to name a couple. Login to each device in your home / office (where ever the IP is located) and change your password to match everywhere. Even if you think your email is not on a device, doublecheck, you would be amazed at how many time’s during my help desk days where a user calls in, “I can’t sign in!” and they almost always have the same issue: they changed a password within the last 30 days that they forgot to change on an old device that is in sleep mode ina drawer somewhere.

Good luck!

After that, you can unban the IP address and optionally add your IP address to a whitelist, but this really shouldn’t be necessary if you discover the reason you ended up on the list and resolve it.

Thank you very much, it is Fail2Ban that has blacklisted my IP. I ran the command iptables -n -L on the command line on the server and it showed that my Router’s public IP is blocked. I think some emails on my machine had incorrect passwords and that is why I ended up being blocked. Thank you, I have been assisted
