After the above message, the game cannot proceed.
os : windows 10 64bit gpu : 3070ti katago 1.13.0 opencl new version.
"Connection Failed" is an interesting error message, it's not one I've seen before. Is it produced by KataGo directly, or is there a GUI or other graphical game/SGF editor or that you are using? Does the same error occur on older versions?
Overwritten and copied to an existing file. It works when I go back to the new folder. Overwritten copy folders are still not allowed. Delete the existing file and do it in a clean folder.
Maybe it's because of the previously used config file. I made a config file with genconfig and used it.
test gui : sabaki 0.52.2 version. gogui 1.5.1 version.
What happens if you run it on the command line?
./katago.exe benchmark -config path/to/your/config.cfg -model path/to/your/model.bin.gz
What error do you get?
In the existing folder you copied, it appears as follows.

Testing using 800 visits. If you have a good GPU, you might increase this using "-visits N" to get more accurate results. If you have a weak GPU and this is taking forever, you can decrease it instead to finish the benchmark faster.
You are currently using the OpenCL version of KataGo. If you have a strong GPU capable of FP16 tensor cores (e.g. RTX2080), using the Cuda version of KataGo instead may give a mild performance boost.
Your GTP config is currently set to use numSearchThreads = 16 Automatically trying different numbers of threads to home in on the best (board size 19x19):

Based on some test data, each speed doubling gains perhaps ~250 Elo by searching deeper. Based on some test data, each thread costs perhaps 7 Elo if using 800 visits, and 2 Elo if using 5000 visits (by making MCTS worse). So APPROXIMATELY based on this benchmark, if you intend to do a 5 second search: numSearchThreads = 5: (baseline) numSearchThreads = 10: +103 Elo numSearchThreads = 12: +122 Elo numSearchThreads = 16: +135 Elo numSearchThreads = 20: +143 Elo (recommended) numSearchThreads = 24: +136 Elo numSearchThreads = 32: +110 Elo
If you care about performance, you may want to edit numSearchThreads in b18_config.cfg based on the above results! If you intend to do much longer searches, configure the seconds per game move you expect with the '-time' flag and benchmark again. If you intend to do short or fixed-visit searches, use lower numSearchThreads for better strength, high threads will weaken strength. If interested see also other notes about performance and mem usage in the top of b18_config.cfg

It comes out well in a clean folder.
Thanks. So I am definitely not sure why there's an issue with your existing folder, but if it comes out well in a clean folder then it sounds like you have a workaround to the issue that solves the problem?
But if you want to investigate further, maybe try seeing if the difference is in the DLL files. Maybe there is a version difference between the DLL files between the two folders, or some other data in those folders?
The lizzie file exists in an existing file. There are other files. There was no problem copying and using the katago 1.12.4 version to the existing file. Maybe there's a conflict in the 1.13.* version.
