Most probably your chain 4 did not report back all chips and therefor the script aborts. Your chain 4 looks like it emits a lot of errors, it might be possible to get that down by increasing voltage further (a setting below 0x50) but from past experience I doubt that.
First check your miners GUI if chain 4 has no crosses. If it has, try rebooting the miner and see if all chips come back to work. If not, try to shut it down and restart it after letting it cool down for 15-20mins.
From there on, I'd recommend to hand-tune chain 4 by ssh'ing to your L3 and running /config/sv manually.
Otherwise you can change the script to use higher voltage by changing
line 73 from 0x50 to a
lower number (meaning to allow the script to try
higher voltages).
Again, I would not recommend this, I have my doubts you'd get much less errors on chain 4 with even higher voltages @450MHz. Try to tune the other three by adding -s 4 to skip chain 4 in tuning and try the best value for chain 4 manually.
