ERROR: APBS failed to generate the result file.

Hello all,

I am running the protocol from here https://github.com/LPDI-EPFL/RosettaSurf/tree/main/scripts/interleukin_benchmark. The .xml script works fine however I keep getting the following error at the end:

core.scoring.sc.ElectrostaticComplementarityCalculator: Ignoring atoms farther than 20 from interface.

core.scoring.sc.ElectrostaticComplementarityCalculator: Trimmed 12133 dots to 487 dots.

core.scoring.PoissonBoltzmannPotential: PB_XK8PX9QS.pqr is successfully written.

core.scoring.PoissonBoltzmannPotential: PB_XK8PX9QS.in is successfully written.

core.scoring.PoissonBoltzmannPotential: APBS failed to generate the result file.  Terminating the program.

protocols.rosetta_scripts.ParsedProtocol: [ ERROR ] Exception while processing procotol:

ERROR: APBS failed to generate the result file.

protocols.jd2.JobDistributor: [ ERROR ]

[ERROR] Exception caught by JobDistributor for job 6m0j_AE_9A

protocols.jd2.JobDistributor: no more batches to process…

protocols.jd2.JobDistributor: 1 jobs considered, 1 jobs attempted in 623 seconds

I was in contact with the first author from the protocol and he suggested that there might be unrecognized atoms causing errors for the APBS calculation and to use the clean_pdb python script on my structure. I did that and the same error is persisting. 

Does anyone have any ideas? I am using the rosetta scripts static release if that changes anything.
