FFXIV Boot Error

[lyvius]

For the last few days I have been receiving the same error but with different codes when trying to launch FFXIV from steam.

"FFXIV Boot Error
Unable to complete version check.
30605 10009 19900 12030"

At this point I have gotten multiple error codes including
30605 20448 10009 10019 and 30605 10009 19900 12029

At first I thought it was my connection, but I am able to play any other game just fine. Another issue i have found is that FFXIV seemed to randomly work in the mornings but not the evenings. Now it doesn't seem to work at all or very sporadically. I have tried everything I could think of and find online when googling this issue. But it persists and I'm getting a little frustrated because there seems to be no logic behind it. At this point I'm suspecting it may have something to do with my provider and their connection to ffxiv servers? I'm not the most tech savvy so please excuse me. But I have no other explanation for it considering that i have installed it on another device and I can not get into the launcher either. Though there it tells me to make sure the game isn't under maintenance and to check my connection rather than just an error code.
If anyone has any suggestions of what might be causing this or fixes, I would be thankful. Though I can not guarantee that I haven't tried it already.

Greetings fellow Eorzean,

If you are unable to update the Final Fantasy XIV game client via Steam on PC, you may be having transmission or connection issues or possible corrupted data. Please try these troubleshooting steps to see if they resolve the issue:

■ Restart communication equipment
Power off your communication equipment for 30 minutes to an hour. Unnecessary data accumulated on the equipment will be initialized, possibly allowing for smoother transmission.

■ Update firmware of communication equipment
Update your firmware, the program running your communication equipment. If the firmware is outdated, your communication equipment may not function properly, so please update your firmware before trying the version update again.

*Consult with the help manual of your hardware when updating firmware. Also, even if your firmware is up to date, rewriting the update may improve the situation.

■ Check settings for security programs and firewalls
There is a possibility that security programs and firewalls are interfering with files related to the game. Please disable these programs before attempting to run FINAL FANTASY XIV. As a last resort, please try uninstalling them for testing purposes.

■ Check security services of your Internet provider
Depending on your Internet provider or service plan, there may be security services included. Please confirm that these security services permit online gaming. If they do not, or if you are unsure, contact your ISP for further details.

■ Close any running applications
Because other applications may interfere with your update, close all other running apps before running the installation file. You can perform a clean boot to ensure no other background programs are interfering with the installation by doing the following:

- Open the Task Manager and select the 'Start Up' Tab. Disable everything here and restart the PC.

■ Remove routers
In order to further diagnose the issue, remove routers and hubs temporarily and connect directly to your modem.

*This may change your connection to a broadband connection. Please consult with your provider for connection settings.

■ Check router settings
Check the settings of security functions (such as SPI) for your router. Also, please forward the ports used for the game. The ports are listed below.

*For details, please consult with the manufacturer of your router.

▼TCP
54992～54994
55006～55007
55021～55040

■ Reinstall FINAL FANTASY XIV
If the installed data has been corrupted, the issue may be resolved by re-installing the program.

Make sure to delete the 'Final Fantasy XIV' folder in the 'My Documents' → 'My Games' folder. You can redownload from the Steam Library.

We hope this information is helpful.

Thank you for contacting the Final Fantasy XIV Technical Support Forums!

Good day. I encountered error “unable to complete version check” today as well. Most interesting part that I launched game this morning as usual without any problems. Just in 30-40 minutes I tried to launch it again and got this error. I tried every single method described on this topic as well as from internet – none helped. I will try to work with this problem a little more in worst case I have to reinstall game and download it all over again – not the most pleasant way and quite time taking.
