I have had quite a number of issues with the installation and overall set up with OSTicket, and I can usually find an answer on this forum or on Google somewhere. For this though, I haven't found anything giving me an inclination.So far for me, I haven't had any problems actually accessing the OSTicket page since I got everything up and running, but it appears certain people I have had test it, cannot seem to access the page, and instead receive this error.However, I have been able to access this on a multitude of devices, such as cellphones, tablets and laptops/desktops just fine. There doesn't seem to be any inclination as to why these people cannot access the page whereas many others can, across different states. Even accessing from my Mac I haven't had any issues. This is what comes up for me and I am able to submit tickets just fine. This is hosted through GoDaddy, and am Running a Wordpress site. It is basic and is still a severe work in progress. I am also fairly new to this sort of thing, so please be kind. PS:I have also read through many guides outlining adding an email to this as a send from address, but for some reason it will not take my Google business email. Any help with that would also be appreciated.
